Quick help topic:

I had a domain full functional and working, but then I realized that the mail server was set to Localhost when it was in actuality a remote server. So I changed it over to remote and saved. Now if I dig from the command line, I still get the localserver as the MX record. I need to clear it so that it looks to the outside world for direction...

How would one go about doing this?

MX records have nothing to do with the remote server setting. To change the mx server you have to change the dns settings for the domain

Ok, I see you and raise you a, "Where/what do I change to maket his work?"

You have to modify the DNS records on the authoritative nameservers for your domain. You can out these nameservers by running

Code:

dig ns yourdomain.com

So I have checked my sources and from the server, it states that the name servers are in the right place (off site). Using MXtoolbox.com, tested and verified that the MX pointed to a mail.domain.tld and then that resolved IP had a correct reverse DNS entry.

But... when I "dig type mx domain.tld" i get the sever's IP address... Thus my rouge record...

Anybody have pointers here? I am not a DNS guy by any means...

Please post the exact dig command you used and the completeoutput that you got.

Sorry to change directions here, but I check DNS and it has updated fully. Now I started looking in the mail logs and I am getting the following in my Postfix logs (edited for privacy):

Code:

Jun  4 09:08:56 ts1 postfix/pickup[12452]: 26662C3409F: uid=33 from=<www-data>

Jun  4 09:08:56 ts1 postfix/bounce[13289]: 26662C3409F: sender non-delivery notification: 36348C340BC

As you can see, it's trying to deliver locally instead of on the appropriate remote server...
